Re: [OSM-dev] The OSM reference map/the default map style on osm.org

2013-08-30 Thread Gregory
I believe when it's referred to as the the reference map people are just
commenting how it's (understandably) become the De Facto standard.
It's on the osm.org homepage and people go there and click edit to change
the map. When they click view they expect/want to see their changes.

For a short time the layer names were displayed as buttons on the map. With
the big redesign/rebuild the buttons are now hidden under an unlabelled
icon and not the first item in the menu. I think that had been helping
people understand the concept of different maps/layers.

This page (and the guidelines it links to) are probably of interest to you:

 Hi,
 during the latest discussion-wave related to the default rendering stiles
 someone (I think Peter K.) used the notion reference map for the OSM
 Slippymap. If this is so, I need some help to understand - in what sense is
 this map the OSM reference map?
 1. Is this the most correct map (the decoration/styling is irrelevant)
 that is possible to be produced/constructed using the OSM source data? or
 2. Is this a map that perfectly reflects the OSM source data-set as is,
 with all logical and other errors?
 The question may sound banal but it is essential to many mappers that are
 extensive users of the OSM source data. These mappers, of course, compare
 their maps with other's especially with the OSM reference map.
 Thanks, Sandor.

Re: [OSM-dev] Default map style on osm.org

2013-08-29 Thread Gregory
I think it would be fun/good to have the default map be a simple wireframe
render (maybe with all the attributes shown as labels, and allowing
overlapping of them). It wouldn't be the best map, but it would point out
we have an incredible amount of data and that's what OSM is firstly about.
The website should then clearly point people to some other layers/renders
though.

I don't think there is a public tileserver that is wireframe though, let
alone one that meets the guidelines for inclusion on osm.org.

  It always amazes me how much the map style influences the mapping

  effect.

 It is an interesting question if that would be indeed the case.

 I believe that one of the main motivating factors for many mappers for
 putting in all the effort of mapping is the reward of contributing to
 something important and big and being able to be proud of the result.
 That is imho why you see those subtle shifts in priority depending on what
 is displayed on the main map. It is simply more rewarding to work on
 something that is perceived to be more meaningful. However, for this to
 work, the main style needs to have a certain popularity among end users
 including being embedded into third party websites. If you now split the
 styles into one presentation style and a data verification style, then
 the data verification style instantly looses that appeal as it will only
 be viewed by a few.

 Recently there has been a lot of talk about gameification of OSM. In my
 opinion, one of the most powerful gameifications of OSM has been to have
 a
 prominent map shown on osm.org and have it update on a minutely basis. It
 really is a rather powerful reward to see your effort being directly
 incorporated into the in production map within minutes which can and _is_
 viewed by millions of people. It is likely a much stronger reward than any
 artificial badge or points and has the advantage it is much less likely
 that people will manipulate things to game the system.  Well, I guess you
 do get gaming the system to some degree as well in form of mapping for
 the renderer.

 So I think the main map really does need to strike a delegate balance
 between, and cater for both the presentation style and data verification
 style despite the fact that they are somewhat contradictory. Imho, the
 solution of cleaning up the low zoom tiles to look good for general use
 and then increasing or at least maintaining the detail on z18, z19 (and
 z20)
 is perhaps the best compromise we can achieve.

 My original request - years ago - came up because I missed additional data
 contained in the GPX files, especially HDOP values and waypoints.
 As far as I see this dump will not contain either; basically you dump what
 anyone could dump by querying the API, you only save the resources for not
 doing it one-by-one, right?

If you followed that argument through then you'd also be able to say that
there's no point in publishing the planet file each week, since it's all
queryable via the API.

The point of publishing all of the GPX data is, just like the planet, when
you're doing something on a larger scale than would be sensible, polite, or
in line with the usage policy for the API.

Re: [OSM-dev] Highway Statistics: counting the number of roads along a junction/roundabout

2013-01-28 Thread Gregory Williams
Just to point out that most junctions and roundabouts won't actually be
members on junction relations. The relations tend to only be used for
complex junctions.

 

I'd also point out that you'll need to keep in mind your handling of divided
highways, where you'll have at least two portions of highway with oneway in
differing directions. I'm sure that you'd want to count the various parts of
the divided highway as just one road though.

 

When I've done something similar in the past I've queried a copy of the data
stored in the usual Postgres schema output by osm2pgsql. I was able to for
points where the roads off of a roundabout intersected the roundabout. It
was hardly a terribly efficient way of going about it though.

Dear all,

I need to generate some statistics on highways. More precisely, given an OSM
file of a city, I would like to find out which is the average number of
roads along a junction/roundabout?
Does anybody has some experience doing that? Given the OSM documentation, it
seems to be, that the only way to do that is by looking for relation's,
right? My intuition is that
if inside a given relation ... /relation, a junction exists, then the
rest of way's inside that relation are the roads along that junction. Is
this reasoning correct?
I'm thinking of using Osmium for that purposes.

 The reason that OSM doesn't do depreciation is that there is no such thing
as the renderer. You don't know if I have a private(or lesser known)
render that relies on a used tag. And it's not limited to renderers, but
editors, data sources, and non-visual uses/applications (such as driving
directors).

Introducing new tags should also take this into account.
For example we had railway=rail and railway=tram type tags. I might make a
map that displays railway=* as a grey line (because I'm more interested in
some other detail but I want tracks for context). For a short time
railway=historic got into popular use. My map would then start showing
railways where they weren't! A better choice for the new tag is
historic=railway because nobody is going to render that as an existing
railway by mistake. Slowly people can start recognising the historic tag if
they wish to.
I can't remember the exact tags in the true version of this story, I think
it was actually to do with stations.

 To be self-contained, it should be sufficient to include the baseURL

 So maybe:
 
optional string writingprogram = 16;
optional string source = 17;
optional sint64 timestamp = 18;
optional sint64 replication_timestamp = 19;
optional string replication_url = 20;
 
 I don't know if the sequenceNumber from state.txt adds any value, if it
does
 then one could throw that in as well.

I think including the sequenceNumber will be useful for making it easy to
determine where to continue replication from once the PBF file is processed.
Just to clarify that the replication_url will need to include the minute /
hour / day as appropriate for the sequenceNumber to apply to the appropriate
sequence, i.e. from the configuration.txt like you say.

Re: [OSM-dev] Fwd: Osmosis - Cutting out a bounding box from a diff file (.osc)

Stéphane,

 

Yes, you’re right in your analysis of how the co-ordinates are stored in the 
slim mode tables. This’ll help confirm it for you:

 

Executing this query against your Postgres database:

select

lon,

lat,

ST_X(ST_Transform(ST_SetSRID(ST_Point(lon / 100, lat / 100),900913),4326)),

ST_Y(ST_Transform(ST_SetSRID(ST_Point(lon / 100, lat / 100),900913),4326))

from planet_osm_nodes where id = 19;

 

Yields:

Lat;lon;st_x;st_y

679034492;-2304090;-0.206971841461138;51.9458701799331

 

 

Request the same node from the API:

 http://api.openstreetmap.org/api/0.6/node/19 
http://api.openstreetmap.org/api/0.6/node/19

 

Yields:

Hi again everybody!

I am trying to implement the post-processing solution: removing all records in 
planet_osm_ways that are completely outside my bounding box. For this I first 
need to find out all the nodes outside the bounding box...

The problem is that the x and y coordinates of planet_osm_nodes seem to be 
plenty wrong. My first record, for instance, has
lat = 450768421
lon = 796483777

I assume that these are in srid 900913 but, if they are, they are way outside 
the limits of the 900913 srs. Actually, I just realised that they are 
systematically wrong by a factor 100. The correct coordinates should be 
something like:
lat = 4507684
lon = 7964837

Have I done something wrong? or is there a known (or unknown?) bug with 
osm2pgsql? The geometries of the useful tables (line, point, polygon, roads) 
seem correct, but the x/y columns of the temporary tableshave this problem...

Cheers

[OSM-dev] Newbie questions, introductions and questions about Mac/Objective-C based mapping/Map View using openstreetmap...

2011-03-09 Thread Gregory Casamento
Kind Greetings and Salutations to everyone,

I'm completely new to this list, so let me introduce myself.  I am
Gregory Casamento, I'm the lead developer of the GNUstep project.

I am currently working on a solution for one of my own projects (not
GNUstep related) which involves routing.   I'm wondering if there are
any Mac (NOT IPHONE OR IOS) based solutions which can do what I'm
after.

I'm fully capable of porting one of the existing iOS/UIKit solutions
to the Mac, but that is an effort I would much rather avoid if at all
possible.

Please let me know if anyone has any input, suggestions etc for me as
it would be very greatly appreciated. :)

Thank you so much, GC

 It's probably not that hard to use PostgreSQL's generate_series() to

 application (or library) to generate them. There, you'd probably
 better decide what kind of grid to use (eg. lon/lat, which
 granularity, or the A/B/C/D  1/2/3/4 grid you often find on printed
 city maps).

I use exactly that for generating some town-scale maps with a grid. The grid 
lines are actually generated as appropriately-sized boxes at regular intervals 
thanks to generate_series(). I use the same squares to generate the street name 
and misc feature index for each map too.

Here's the code as it stands at present, but I know it needs tidying to not 
have a hard-coded box size in it:

insert into grid (map, column, row, way)
SELECT
 'Canterbury',
 chr(65 + x_series) AS column,
 y_series + 1 AS row,
 translate(way, 113562 + (x_series * 1603), 524 + (y_series * 1603)) AS way

SELECT GeomFromText('POLYGON((0 0, 0 1603, 1603 1603, 1603 0, 0

 Filters are just search queries, so you can do e.g.:

boundary=administrative -(highway=* | waterway=* | natural=*)

 If you want to hide boundary relations you can put that query in a ()
 and OR it together with one that searches for ways that are part of a
 boundary relation, use the child/parent operators for that.

Re: [OSM-dev] Open Social Routing Idea: Request for preliminary comments

2010-04-20 Thread Gregory
It sounds good.
Anyone who knows about routing knows that it takes a crazy long time to be
sure of the perfect route. This could be a way for the program to say I
know the best way to get most of the way, because Jane told me she goes this
way..
Adding a load of sample routes in one area, and with a good weighting on
provided routes, it would be interesting to see how the program faired to
other routing algorithms that.

Are you going to look at motoring routing? Walking routing might be just as
interesting (and more easy to get people's routes added). I walk around
university a lot, sometimes two routes look exactly the same length but I
take the route through a park because it's nicer and makes the journey feel
shorter. Sometimes I go one way because it just has a few steps, returning I
go another way because it's downhill.

 @Ivan: I agree.
 The more people using my favourite route, the slower I will get forward, so

 But: tell the user to make a perfect route for her purpose if she supplies
 the service with detail information such as car type, personal driving
 style, comfort preference, urgency, and, of course, starting time and
 personally expected arrival time. And don't forget about the feedback next
 time she logs in again. (think carefully about the validity of the result)

 last.fm names this 'skobbling' and gives you recommendations, groups user
 types and creates correlations to form groups by similarity of preferences.

 The idea is not bad, but I don't expect it to grow successful, especially
 because the project's scope is short-term. You need a deep breath to get it
 all sexy and charming enough for average people to use. Without a wide
 userbase such a service won't get any value.

 Creating the toolset services like this could be based upon looks
 promising, though.

 Hi,

 I'd like to know if there are structured mapping files for languages
 from tags to labels - such as a mapping
 for
spanish
 from
highway=traffic_signals
 to
Semáforo

To check we are on the same page:
OSM data should be in (GB) English so that map renderers and tools don't
have to account for all the languages in which people add data. but not
everyone knows what highway=traffic_signals means, so you want a translation
to a label. At the moment the Spanish translation of the wiki map features
page maintains the English tagging name, but the description/explanation is
in Spanish (sometimes all you need is the translation of 'traffic signals').


Although the wiki contains the information[1] its not totally structured
 there. So maybe someone is maintaining a set of e.g. XML files for that
 purpose?

I believe not yet, but I can see the uses. Editors could work in different
languages, so you add a highway=semáforo but the map editor translates it to
highway=traffic_signals before uploading it to OSM. Editors and other tools
could share this OSM-some_language lookup file so that if there is new
tagging (or someone gets round to translating more tags) then all the tools
update with the translations.

I think there might be language packs/plugins for the JOSM editor. I'm not
sure what they do, or how that information is stored though.

Sorry I pathetically only know English, I should make a start learning
important bits for SOTM...

Re: [OSM-dev] [Talk-GB] OSM shortlinks problem

2010-03-29 Thread Gregory
Forwarding to dev as requested.
I think it has been noticed already, it can also break in applications such
as twitter. But is anything going to be changed?

I understand avoiding the ending character from being non-alphanumeric(not
letters or numbers) would mean a serious rewrite of how the shortlinks are
made/decoded. How much longer would short links be if all digits were
alphanumeric only?

Also the code is public so people can create these themselves or decode
them, has anyone actually done that?

 least, this seems to move the centre slightly and switch from zoom level 17
 to 18.

 For example this:
 http://osm.org/go/euut_VcMR-

 Gets interpreted as this:

 Is there any chance the shortlinks could avoid ending in a punctuation
 mark?

Well I suggested that you remove problematic symbols, and just use A-Z, a-z,
0-9 if need be.

Hmm, sorry Matt I see you only sent to Dev so might have missed the
discussion on Talk-GB.
It was said (if we have powers over Google, Microsoft, and other big e-mail
applications) we tell them to change...
It's also allowed behaviour. '-' is a valid URI character, so any user
agent that chops them off the end of a URI is broken. I realise that
doesn't help the people using them, but it would be better to fix the
problem in the correct place.

Robert Scott referenced RFC4648 base32 and said we could change it to =
perhaps (changing it back and breaking twitter again!).

Steve Doerr wondered if replacing it with %2D would solve it. I'm not sure
at what point it would be best to do this (in the link or manually).

It sounds like there will always be problems so I'm probably going to step

Divide the sections using impassable barriers such as railways and rivers,
then by main roads. The side roads of main roads are less likely to be dead
ends, so you don't even need to pass down the main road. In the worst case
there is a person either side of the main road doing something odd (noting
street signs) and they spot each other and smile/wave. It's nice to bump
into mappers, and at London  mapping parties I make a note who is doing
surrounding slices so I can keep an eye out for them.
This planning is a lot easier when you have the full road network to look at
before hand. You can identify road sections you don't need to go down.

Why don't you just man-up (or nerd-up) and go full out with getting house
numbers.
http://wiki.openstreetmap.org/wiki/Proposed_features/House_numbers/Karlsruhe_Schema
This would avoid missing name changes, and catch things like one-ways,
shops, and all the other amenities which makes OSM rich. Similar to the
London Mapping Parties. You would want to make smaller areas, but it can
also be suitable for evening mapping as smaller areas = can be closer to a
meeting point.

I remember being told it was very important for imports, such as NAPTAN,

that ref).


Back to the original poster, Andreas. I am still unclear about some things,
are you wanting to bring the data back out of OSM to use in your

then we might be able to understand the best way for you to add to OSM.

It would be interesting to know the rough geographic area your data covers.
We can then see if the area is near blank or has some dedicated mappers that
will be keen to help manually edit your import (e.g. check for imports).
Some people here have also requested an extract of the data to look at the
quality, or what it contains.

Hopefully your not getting overwhelmed by the replies here. Welcome to the

It's also important to repeat the argument that people post diary entries
without ever editing the map. OpenStreetMap is no longer just for mappers.

I see the best solution to be a moderation queue for the first 1-3 posts. If
x number of previously passed members mark your 3 posts as okay, they become
visible and you pass the test. The moderation queue could also serve as a
place to see new users and help them out (as I like to do from time to
time). I think it would be best to avoid having a select moderation group,
but rather crowd source the moderation to any user that has passed the test.

I also like the OSM-related photo question, but only for the potential humor

Which of these photos is a mapper in trouble? - correct one is a photo of

Where is a fun place to be? - correct answer is some people holding an OSM

Hmmm, could this be the issue?


http://svn.openstreetmap.org/sites/rails_port/app/models/relation_tag.rb:
validates_uniqueness_of :id, :scope = :k

shouldn't that read:
validates_uniqueness_of :k, :scope = :id

 All,
 
 
 
 Since API v0.6 went live earlier this morning I have created a brand
 new relation and then subsequently corrected a typo I’d made to one of
 the tag values. Subsequently looking at the values of the tags on the
 relation I see that they’ve ALL been changed to the value I changed on
 just one of the tags, rather than only that tag being updated. The
 relation in question is 115694. I was hoping that a quick dump of the

 indeed. i don't think frederik was suggesting that features are
 removed, just warn the user that they might have selected more objects
 than they thought.
 
 i think its a good idea. if the limit is settable in expert
 preferences then so much the better. it helps protect inexperienced
 users and doesn't get in the way of advanced users.

Yes, I'm for having a warning with a configurable threshold. It'd be
great to have a warning if you attempt to move a similarly large number
of objects in unison as well, but I'm not quite sure how that'd operate
since a pop up window would take the focus away from the drag operation
that's in progress.

Re: [OSM-dev] Are there a feature rendering rules for Mapnik?

2009-01-27 Thread Gregory Williams
Ivo,

 

Casing is the border of the road, whereas the fill is the colour in the centre. 
You’ll see that these are two overlapping lines, with the casing slightly wider 
than the fill, such that just either edge shows through once the fill is drawn 
on top.

 

Cheers,

 

Gregory

Hi,





The nicest way I know is using some xslt from here:
https://lists.berlios.de/pipermail/mapnik-users/2008-June/000986.html

This produces a neatly formatted page listing all the layers, styles and
rules with min/max zooms and mouse-overs with details of css parameters
etc.

 

I took a closer look now and it is really neat, but I don't understand this:

 

minor-roads

  minor-roads-casing  

5 000

1 000

☡

([highway] = 'secondary' or [highway] = 
'secondary_link') and not ([tunnel]='yes' or [tunnel]='true')

  CSS:

  stroke: #a37b48 stroke-dasharray: stroke-linecap: round 
stroke-linejoin: round stroke-width: 17;

  



  minor-roads-fill   

5 000

1 000

☡

([highway] = 'secondary' or [highway] = 
'secondary_link') and not ([tunnel]='yes' or [tunnel]='true')

  CSS:



  stroke: #fdbf6f stroke-dasharray: stroke-linecap: round 
stroke-linejoin: round stroke-width: 14

 

Where is the difference between fill and the casing? The conditions are the 
same, aren't they?

 

What do I miss here?

 

Thanks

Repro steps:

(1) Ensure that you're not logged into the website.
(2) Open http://api06.dev.openstreetmap.org/ in two separate web browser
tabs. Let's call them A and B.
(3) Log in using the site in tab A. Works fine.
(4) Switch to tab B, which still shows the state from before the

Re: [OSM-dev] [Patch] Experimental extra symbols for mapnik layer

2008-09-21 Thread Gregory
2008/9/18 Brian Quinion [EMAIL PROTECTED]

 Adding icons need to be done careful moderation and adding any
 significant number runs the risk of making the default map unsuitable
 for some purposes (for instance a hotel chain would not want other
 hotels appearing on their maps!).

Or it could be better. I can display all POIs except hotels, take a
screenshot, then add just 1 icon(or company logo) for my hotel.

I seem to have misunderstood something, and thought someone suggested having
multiple layers of POIs. Slowing down to type and perhaps that suggestion
made, sorry if it's an outrageous one.
But your icon set looks like it could be easily split into a few layers,
brown layer(food/pubs) etc.
I also really like the transparency on the beer icons and generally.


 I'm also not particularly happy
 with the placement of the icons - I'm currently working on a patch to
 mapnik to allow icons to be 'nudged' into clear space to improve the
 cartographical result - I'm also trying translucency and various other
 effects.  Suggestions welcome.

That would be a brilliant patch, something I think we all want as it will
avoid the need to move the node far enough for the way. Sometimes/people
will wait a week to look at the render in case they didn't keep nodes/ways
far enough apart.

I can also think of other alternatives too.  For instance we could
 provide 2 mapnik layers (one naked, one with icons) or try to find
 some way to overlay individual symbols browser side without too much of a
 performance hit.

I wonder if the standard map user is happy with switching between layers, as
I've also wondered if people spot/click the + to find the osmarender and
cycle map layers.


It's interesting to see the work people are doing on styling the map dta.
Much better than my quick mucking around with Kosmos:
http://www.livingwithdragons.com/hampton
If you zoom in on 'High Street' near 'Arundel Close Open Space', you can see
how work needs to be done for a row of shops. Most of the names end up
appearing over the wrong icon.
Second half of this blog post is about that map:

[OSM-dev] Problems with JOSM

2008-09-12 Thread Gregory
Hi,
I probably should of noted down what version I was using (I think it was the
latest around june) before I decided to download the josm-latest.
It doesn't work now and I've tried finding something from
http://josm.openstreetmap.de/download/ that does work. I've deleted my
prefrences file to avoid plugins or things like that causing problems.

401 and higher (tried a file about every hundred):
An unexpected error has been detected by Java Runtime Environment
Program doesn't open

352:
Program opens, but when I open a gpx file it closes immedietly and the
command prompt gives the same message os 401.

345:
Program opens, the welcome message text is wrapping to a width of about
100px. Same problem as 352.

346:
Same problem as 352.

338:
Same problem as 352.

josm-1.5 worked but of course uses the 0.4 api so can't download osm data.

What should I do now to try and get it to work?
I'm using Windows XP Pro.

I could send the contents of the java error report to someone.

Can this be removed from the plugins list? (as it's no longer needed/used)
Unless there is a reason it still gets listed, I'm not bothered it justs
seems to make sense to remove it.

Thanks shaun.
Thanks guys on IRC when I was worrying.

 Hi,
 I probably should of noted down what version I was using (I think it was
 the latest around june) before I decided to download the josm-latest.
 It doesn't work now and I've tried finding something from
 http://josm.openstreetmap.de/download/ that does work. I've deleted my
 prefrences file to avoid plugins or things like that causing problems.


 Doh, seems I cannot read.

 Using java 6 here on Ubuntu I have not problems with latest (945).

 Can you please run java --version and send the result, that should give
 some more info.

Re: [OSM-dev] openstreetbugs to the main-side

2008-08-29 Thread Gregory
With Potlatch it shouldn't be hard to add something, although this does
require registering and maybe a bit of reading.
I had wondered before why there wasn't a link from the main map, so I'm all
for someone adding it.

2008/8/29 John07 [EMAIL PROTECTED]

 Hi,
 some days ago somebody started contributing to osm here in my osm-area.
 He helped to correct the map although he didn´t edit any data. He simple
 used openstreetbugs.
 If you speak with osm-newbies they often say that it is too dificult to
 edit the map. Then i say, hey, look at openstreetbugs, this is really
 simple.
 Therefore i think we have to put openstreetbugs on the main-side
 www.openstreetmap.org
 Either we make a big link to openstreetbugs or we integrate
 openstreetbugs into the main-site. I think the second solution would be
 much better, but the first one is easier.
 So what do you think about this? And how could this be done?

 Jonas
 P.S. Sorry for my poor englisch.

Re: [OSM-dev] real-time traffic map

2008-08-20 Thread Gregory
2008/8/20 Rogier Wolff [EMAIL PROTECTED]



 I would expect that the userbase of OSM is too small to make accurate
 travel-time estimates, based on (live) GPS tracks. So I'm afraid
 that in practise it won't work.

 And even less is the number of users that have some GPS system capable of
communicating live with a server. We record the GPS track and later in the
day/week upload it onto our computers.
I suppose I could use my mobile phone to send my location, but
a) that would be a cost on my phone bill
b) maybe I don't want you knowing where I am and how fast I'm going

Re: [OSM-dev] Autocorrectable data inconsistency

In which case, my apologies for misinterpreting, and I completely agree that 
duplicated nodes serve no purpose whatsoever.

 You have misinterpreted the topic. Its about having the exact same node
 several times one after each other in a way.

  As I see it there is a case, at least on a practical level, for
 storing a series of nodes along a straight line in a way. Imagine a
 very long straight road that crosses multiple z12 tiles. If this were
 stored in its simplest geometric form then there wouldn't be nodes
 within (or potentially in the extra margin that [EMAIL PROTECTED] downloads) 
 a z12
 tile. Therefore the tile would be rendered as if that road doesn't
 exist.
 
  Similarly if somebody working in an editor doesn't download a
 sufficiently large area to encompass at least one of the way's nodes
 then they may get the impression that the road hasn't yet been entered
 into OSM's data. That might even lead to them drawing their own road
 along the same path!

I don't see any.
   
I could write a script to korrect the existing ones. Do the
   sequence_ids
have to be in sequence (which means the ones above need to be
 shifted
down) or does a simple DELETE per dupe do it.
  
   All changes should be done through the API. Do changes on the
 database
   directly only leads to inconsistencies. The API does not expose the
   sequence number, so the order alone is fine.

 Well if you give us more than about two seconds after they are
 installed then we might be able to tell you...

 Seriously, the only one doing anything at the moment is idris which is
 a dedicated Atom based machine generously provided by Bytemark to
 replace the virtual machine they had previously been providing. It is
 now running all the services (wiki, trac, svn, mailing lists) which
 used to be on the virtual machine.

 Of the others, the three G5 machines (draco, sarel and norbert) will
 probably be used to replace the current rails application servers
 which will allow to run significantly more rails daemons. There is
 a small amount of hardware reconfiguration to be done first though.

 Of the two G3 machines (puff and fuchur) one will probably be used
 to replace the current frontend web server and we don't currently
 have an immediate use planned for the other one.

Re: [OSM-dev] Devsvn accounts

2008-03-08 Thread Gregory Williams
If I record to the SD card then it includes the date / time in the
filename. If I use the Windows software to download just the tracks and
waypoints in the internal memory then it uses a filename based upon the
serial number. I use the latter if I've only done a small amount of
mapping (i.e. not exceeded the internal memory), because it does the
gpsbabel step to convert to GPX as part of the process, thus saving me a
few seconds.

The GT-11 I have (well off for a repair just now), also included the  
date and time in UTC for the file name. I take it that your firmware  
only creates one log file, and not a new one each time the GPS is  
started like the firmware I was used to.

TrekBuddy and TrackMyJourney when setup to auto log both use the date  
to produce unique files within that one directory that the files are  
stored. I just haven't had the experience of doing things differently  
how some others do them.
